    SBC 383 advise

    I am building a pro street 70 Z28 and using a 383 that was built for another car with an automatic. I am using a 4 speed. So, since the engine was balanced, will I need to get the fly wheel 0 balanced? Also, any comments on RHS Aluminum Heads. Good..Bad???

    383

    If the engine had an external balanced flexplate you should need the same with the flywheel .take the flexplate to a reputable engine shop (hopefully the one that originally balanced your motor) and have the two matched up. :wink:
